Steen.

BTW Very nicely build

I think the good ol' TO247 IS good ol' IRFP240 - but look just above the RCA input socket in the top-down picture - three small legs going in under the heatsink, and a small nut on top......mabye it's the Jfet ??

Cheers !

The 3rd Mosfet is for Voltage Regulation like I said in another thread. Yes I'm 100% those 3 legs sticking out is that of the Jfet sandwiched between the pcb and the flange with the heatsink surface facing up of course.

Trust me...these things are much, much smaller than a TO-247. They're about the size of your pinky fingernail. I haven't looked at these pictures, but from pictures I saw before I seem to recall that the JFET appeared to be sandwiched between the PC board and the heatsink flange--a stealth part.

Hi nice review,who did it, first off this product is pure class-a,
no doubt about!,i was expecting to hear good words about it
there has been no mention of how it sounded at all, i am disappointed because my pure class-a s sound like super sonics

I wish Mr Pass good luck in the field of pure A it would be a tough
field to compete in in the future
